[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] A braking device for electromagnetic catapult, such as Figure 1 and Figure 2 As can be seen, the complete braking system in the embodiment comprises a second guide wheel 21 arranged to rotate vertically in the horizontal direction, a third guide wheel 22 arranged to rotate horizontally in the horizontal direction, a fourth guide wheel 23 arranged to rotate vertically and at the same level as the third guide wheel 22, and a first guide wheel 2 arranged to rotate horizontally and at the same level as the second guide wheel 21. The ends of the intercepting rope 24 pass through the second guide wheel 21, the first guide wheel 2, the two third guide wheels 22, and the fourth guide wheel 23, and are connected to the output end of the arresting mechanism. The intercepting rope 24 between the two second guide wheels 21 is used to intercept the tractor. In the embodiment, the intercepting rope 24 is a steel cable.

[0028] Further, combined Figure 3 It can be seen that a slide rail groove 11 is provided on the mounting plate 1, and a first guide wheel 2 is slidably provided in the slide rail groove 11;

[0029] And on mounting board 1:

[0030] A first hydraulic damper 3 is fixedly installed and arranged coaxially with the slide rail groove 11;

[0031] A first swinging member 4 is rotatably provided, and a first connecting member 5 is rotatably provided between a first end of the first swinging member 4 and a first guide wheel 2 shaft rotatably provided with a flying disc 10;

[0032] A second swinging member 6 is rotatably provided, and a second connecting member 7 is rotatably provided between a first end of the second swinging member 6 and a second end of the first swinging member 4;

[0033] A third connecting member 8 is rotatably provided, and a fourth connecting rod 81 is rotatably connected to the second end of the second swinging member 6 , and the third connecting member 8 is slidably connected to the output end of the first hydraulic damper 3 .

[0034] In the above technology, when the intercepting rope 24 is contacted by the tractor and pulled toward the moving direction of the tractor, the first guide wheel 2 is pulled toward the side of the first hydraulic damper 3. During the process, the first connecting member 5 pushes the first swinging member 4 to rotate, and after the rotation of the first swinging member 4, the second connecting member 7 will push the second swinging member 6 to rotate. At this time, the third connecting member 8 will be pulled away from the side of the first hydraulic damper 3 through the fourth connecting rod 81 to deflect, thereby pulling the output end of the first hydraulic damper 3 and braking together with the blocking.

[0035] As an embodiment further provided by the present invention, the mounting plate 1 is rotatably provided with a second hydraulic damper 9 , and the output end of the second hydraulic damper 9 is rotatably provided with a sliding member 91 sliding on the first end of the second swinging member 6 .

[0036] Furthermore, the force-bearing stroke of the second hydraulic damper 9 is contraction.

[0037] Specifically, in the embodiment, when the second swing member 6 rotates, the second hydraulic damper 9 is lifted up by the first end of the second swing member 6 and subjected to force, so the force stroke of the second hydraulic damper 9 at this time is contraction, and cooperates with the first hydraulic damper 3 to perform braking.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
